fix(yabloc_pose_initializer): disable downloading artifacts by default

[esteve]

Description

Other packages that use artifacts, have a DOWNLOAD_ARTIFACTS option, so that they can be built without access to the internet (e.g. when built with Debian's sbuild). This PR adds such option and defaults it to off.

See autowarefoundation/autoware-deb-packages#18

@esteve Hi! I think this PR looks good.
However, I noticed that lidar_apollo_instance_segmentation also downloads files using CMake, but I'm curious why it doesn't result in any errors. If you don't mind, could you please provide an explanation? I would appreciate it.

[esteve]

@KYabuuchi thanks for the feedback. We're currently not building lidar_apollo_instance_segmentation as part of https://github.com/autowarefoundation/autoware-deb-packages, because it depends on TensorRT (https://github.com/autowarefoundation/autoware.universe/blob/main/perception/lidar_apollo_instance_segmentation/CMakeLists.txt#L15).

However, if we ever include it as part of the autoware-deb-packages repository, we'll have to disable automatic downloading of the artifacts. Moreover, we have #3137 which does disable downloading artifacts in lidar_apollo_instance_segmentation and other packages.

[KYabuuchi]

I understand. It makes sense now. 👍

@KYabuuchi thanks for approving this PR, I will merge it and add it to the list of PRs that disable downloading artifacts by default.
